Description

Technical Field

[0001] The invention relates to the technical field of bridge maintenance spraying, and in particular to an automatic spraying maintenance system for cantilevered beam sections of a rigid frame bridge. Background Art

[0002] Cantilevered beam sections, especially in steel structure bridges, refer to the bridge beam sections constructed by cantilever casting. The cantilever casting method is a construction method in which a working platform is set up on both sides of the pier, and the cement concrete beam body is cantilevered in sections to the mid-span in a balanced manner, and prestressed section by section. This method allows the bridge beam section to be gradually extended until the entire span of the bridge is completed. The construction of the cantilevered beam section is carried out section by section, and each section of the beam body is cast on the basis of the previous section of the beam body. This construction method allows the bridge beam body to be gradually extended until the entire span of the bridge is completed. During the construction of the bridge, the concrete of the bridge needs a period of time to harden and increase its strength after pouring. In this process, if the concrete surface loses water too quickly, it is easy to crack. Spray curing can form a moist protective film by spraying water mist on the concrete surface, which effectively slows down the evaporation rate of water and prevents concrete from cracking.

[0003] Among them, the patent with announcement number CN210127197U discloses an intelligent automatic spraying maintenance system for cantilevered beam sections of continuous rigid frame bridges, including a water storage tank arranged on the bridge deck, the water storage tank is connected to the main water pipe via a booster water pump, and the main water pipe is connected to the spray pipes arranged on the hanging baskets at both ends of the bridge deck; the spray pipes are respectively arranged on the front upper cross beam, the inner sliding beam and the outer sliding beam of the hanging basket;

[0004] When the structure is in use, spray maintenance can be achieved on the bridge deck, inner box bottom plate, top plate and web, as well as the bottom surface of the flange plate and the outer surface of the web by installing spray pipes on the hanging basket components, namely the front upper cross beam, the inner sliding beam and the outer sliding beam. The system is not affected by human factors, has comprehensive maintenance and no danger of high-altitude operation. However, when the structure is in use, it is not easy to spray the cantilever beam sections in different areas, and it is not easy to adjust the appropriate range according to needs during spraying, which is not convenient enough when in use.
